Hi guys, I'm new into kotlin, I have a few questions: 1. annotationProcessor or kapt? 2. Butterknife or kotlin android extensions?

kotlin extensions

hey guys, have anybody tried https://developer.android.com/topic/libraries/architecture/index.html ? i'm not sure how to fetch resources (strings, colors etc) inside of

ViewModel

. Of course we can use

AndroidViewModel

which receives

Application

as a constructor param. But in this case we expose android implementation and can't easily test our

ViewModel

with unit tests (without mocking the app)

I don't think you should fetch resources like strings and colors inside the

ViewModel

yep. i used to

ObservableField

everywhere 🙂 btw i hope they will add some delegated properties support for

ObservableField

, so we can use fields as

textLabel = "hello world"

instead of

textLabel.set("hello world")

whoops 😄

hey there i need to know why it's better to use kotlin over java se8 on android ? also does kotlin has it's own compiler or it is fully depended on jvm ?

I had one constants file in Java, where all my "public static final String" were declared. Now I converted that to Kotlin using the AS 3.0 tool. The generated file converted public class -> object -- Why not class? public static final String -> val -- It is understandable. But the places I was using those constants changed to: Constants.TEST -> Constants.INSTANCE.getTEST() -- Any better way to achieve this? All my switch case fails as they need String literals not String object. I know when in Kotlin, but those classes are Java and can't convert whole project in Kotlin at one shot. As I am new to Kotlin.

I am completely new to Kotlin and this is my 1st class in Kotlin. So your help is appreciated.

Even the automatic generated unit tests in a newly created project fail...

was just looking at Dagger, the scopes seem to lack something comparable to a conversation? Activity scope is not great because the Activity is not remade each time, so for instance, a wizard would not work with that scope, correct?

i have a fragment, and a mapView, and in my fragment’s onstart, I’m trying to call mapView.onstart

Ayy wadaap, tying out android development with kotlin and can't figure out of how to open new activities. I'm guessing it's the same as it is with java, so create new intent, start intent

In means of annotations

is there away to see the member count of this channel before I/O

are kotlin junit tests supported in android studio 3.0? Im always getting class not found.

So, we don't need to apply to Kotlin plugin anymore with the Android Gradle plugin v 3.0?

Where can I get more information about this?

a return statement always returns from the nearest block.. so if you had something like

fun something(x: List<String>) { x.forEach { ...; return something; }}

, you would be returning from the inner lambda

@orangy not directly related to Kotlin, but I wonder if you could comment on the 3.0.0-alpha1 plugin and its interaction with IntelliJ - I posted this (https://www.reddit.com/r/androiddev/comments/6c71av/using_android_gradle_plugin_300alpha1_with/) to /r/androiddev and got a response from the Android Tools team stating that integration with IJ will likely break further until AS 3.0 is released and JB pulls in the appropriate changes. I use IntelliJ Ultimate day-to-day and would prefer not to have to switch over to AS 3.0 for Android projects.

Also all Mockito.any() calls throw when the parameter is not nullable

The new room persistence is annoying in kotlin :( hooray for kotlin/java interoperability

@orangy could you comment on this https://kotlinlang.slack.com/archives/C0B8M7BUY/p1495379879095455?thread_ts=1495379501.078221&cid=C0B8M7BUY ? For constructor parameters annotation processors work well, I was under the impression that regular methods work fine as well. Is it something that should be reported?

How can I comment if I don’t understand the question? Please don’t mention anyone from [JB] team if you are not absolutely sure we are the person to ask. Also, it’s Sunday, so most people are with families, friends, or traveling.

There are 165 channels, any recommendations?
